Fix __key_link_end()'s attempt to fix up the quota if an error occurs.
There are two erroneous cases: Firstly, we always decrease the quota if
the preallocated replacement keyring needs cleaning up, irrespective of
whether or not we should (we may have replaced a pointer rather than
adding another pointer).
Secondly, we never clean up the quota if we added a pointer without the
keyring storage being extended (we allocate multiple pointers at a time,
even if we're not going to use them all immediately).
We handle this by setting the bottom bit of the preallocation pointer in
__key_link_begin() to indicate that the quota needs fixing up, which is
then passed to __key_link() (which clears the whole thing) and
__key_link_end().

Relying on the access time of peripherals is unreliable - it depends
on the speed of the CPU and the bus. On Versatile Express, these
timeouts were expiring, causing the driver to fail.
Add udelay(1) to ensure that they don't expire early, and adjust
timeouts to give a reasonable margin over the response times.

The EP93xx C and D GPIO ports are multiplexed with the Keypad Interface
peripheral. At power-up they default into non-GPIO mode with the Key
Matrix controller enabled so these ports are unusable for GPIO. Note
that the Keypad Interface peripheral is only available in the EP9307,
EP9312, and EP9315 processor variants.
The keypad support will clear the DeviceConfig bits appropriately to
enable the Keypad Interface when the driver is loaded. And, when the
driver is unloaded it will set the bits to return the ports to GPIO mode.
To make these ports available for GPIO after power-up on all EP93xx
processor variants, set the KEYS and GONK bits in the DeviceConfig
register.
Similarly, the E, G, and H ports are multiplexed with the IDE Interface
peripheral. At power-up these also default into non-GPIO mode. Note
that the IDE peripheral is only available in the EP9312 and EP9315
processor variants.
Since an IDE driver is not even available in mainline, set the EONIDE,
GONIDE, and HONIDE bits in the DeviceConfig register so that these
ports will be available for GPIO use after power-up.

Timers on Versatile Express mainboard are used as system clock/event
sources. Driver assumes that they are clocked with 1MHz signal.
Old V2M firmware apparently configured it by default, but on newer
boards one can observe that "sleep 1" command takes over 30 seconds
to finish, as the timers are fed with 32kHz instead...
This patch performs required magic and also removes code clearing
timer's control registers, as exactly the same operations are
performed by the timer driver few jiffies later.

As no one seems to really know which configuration options tie up with
which boards, I thought I'd do some investigation and try to work it
out. After discussion with some folk in linaro, I think I have this
nailed.
The names are updated to use the name on the front of the appropriate
board user guide for the various baseboards, which I've taken to be
the official name for each board.
I haven't significantly updated the descriptions for the tiles as that
is even less clear - as far as I can see on ARMs website, there is no
Cortex-A9 tile for Realview EB - only ARM11MPCore, ARM1156T2F-S,
ARM1176TZF-S and Cortex-R4F. So exactly what this 'Multicore Cortex-A9
Tile' is...

Fix two section mismatch warnings in the platform SMP bringup code for
Realview and Versatile Express:
WARNING: arch/arm/mach-realview/built-in.o(.text+0x8ac): Section mismatch in reference from the function write_pen_release() to the variable .cpuinit.data:pen_release
The function write_pen_release() references
the variable __cpuinitdata pen_release.
This is often because write_pen_release lacks a __cpuinitdata
annotation or the annotation of pen_release is wrong.

lcd_device_register may return ERR_PTR, so a check is added for this value
before the dereference. All of the other changes reorganize the error
handling code in this function to avoid duplicating all of it in the added
case.
In the original code, in one case, the global variable fb_buffer was set to
NULL in error code that appears after this variable is initialized. This
is done now in all error handling code that has this property.
The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@r@
identifier f;
@@
f(...) { ... return ERR_PTR(...); }
@@
identifier r.f, fld;
